【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、自動車のプレス成形品等の自由曲面を有する
物品を基準位置に固定する場合に好適な固定具に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a fixture suitable for fixing an article having a free curved surface such as a press-molded article of an automobile to a reference position.
従来、自由曲面を有する物品（以下ワークＷという）の
各部の寸法測定あるいは所定の追加工を行う場合に、こ
のワークＷを固定するために第７図に示すような位置決
め治具Ｄが用いられていた。この位置決め治具Ｄは、所
定の面積を有する定盤Ｃの上面にそれぞれ所定の高さを
有する支持柱B1〜B3を立設し、これらの上端に先端部が
円錐形状である受具A1〜A3をそれぞれ付設してなるもの
で、各受具A1〜A3の上端T1〜T3は定盤Ｃの上面から規定
の高さとなるよう予め設定されていた。Conventionally, a positioning jig D as shown in FIG. 7 is used to fix the work W when the dimension of each part of an article having a free curved surface (hereinafter referred to as the work W) is measured or a predetermined additional machining is performed. Was there. In this positioning jig D, support columns B1 to B3 each having a predetermined height are erected on the upper surface of a surface plate C having a predetermined area, and a receiving end A1 to a tip of which has a conical shape at their upper ends. A3 are attached respectively, and the upper ends T1 to T3 of the receiving members A1 to A3 are preset so as to have a prescribed height from the upper surface of the surface plate C.
このように構成された位置決め治具Ｄを用いてワークＷ
を基準の位置に固定するためには、ワークＷの基準点P1
〜P3のすべてが受具A1〜A3の上端T1〜T3に接触している
必要がある。もし一箇所でも浮いている所（隙間）があ
ればワークＷは基準の位置からずれていることとなり
（図中一点鎖線で示す位置）、精度の高い寸法測定ある
いは追加工等ができなくなってしまう。このために従来
は、載置されたワークＷの上に重りを載せたり、或いは
適当な磁力を有する磁石を載せてその磁力を利用してワ
ークＷを受具Ａの先端部に吸着させたりする等の方法に
より上記隙間をなくしていた。Using the positioning jig D thus configured, the work W
Is fixed at the reference position, the work W reference point P1
It is necessary that all of ~ P3 are in contact with the upper ends T1 to T3 of the receivers A1 to A3. If there is a floating part (gap) even in one place, the work W will be displaced from the reference position (the position shown by the alternate long and short dash line in the figure), and it will not be possible to perform accurate dimension measurement or additional machining. . For this reason, conventionally, a weight is placed on the placed work W, or a magnet having an appropriate magnetic force is placed and the work W is attracted to the tip of the receiver A by utilizing the magnetic force. The above gap was eliminated by the above method.
しかしながら、上記した従来の方法でワークＷと受具Ａ
との間の隙間を無くそうとする場合には、不安定な部位
に重りを設置することからその作業に手間取り、また危
険でもあった。このことは受具Ａの数が多くなるほど顕
著なことであった。However, the work W and the receiver A are processed by the conventional method described above.
When trying to eliminate the gap between and, it was time-consuming and dangerous because the weight was installed at an unstable part. This was remarkable as the number of the receiving tools A increased.
また、磁石によって受具Ａの先端にワークＷを吸着する
方法であっても、受具Ａの先端部が円錐形状であること
から強固な固定をすることは困難であった。Even if the work W is attracted to the tip of the receiver A by a magnet, it is difficult to firmly fix the workpiece A because the tip of the receiver A has a conical shape.
更に、上記受具Ａの先端部の形状は、理想的には尖角状
であることが望ましいが、実際にはある大きさの球状で
あることが一般的である。このため第８図に示すよう
に、載置されるワークＷの傾斜が大きくなるほどワーク
Ｗと受具Ａの接点Ｓ（支持点）は下方に移動することと
なる。従って、予め基準の高さに設定されている受具Ａ
の先端T1〜T3から下方にずれた位置でワークＷが固定さ
れることとなり、このことからもワークＷの正確な寸法
測定あるいは追加工を行うことが困難であった。Further, the shape of the tip of the receiving tool A is ideally preferably a sharp shape, but in reality, it is generally a spherical shape having a certain size. Therefore, as shown in FIG. 8, the contact S (support point) between the work W and the receiving tool A moves downward as the inclination of the work W to be placed increases. Therefore, the receiver A that is set to the standard height in advance
Since the work W is fixed at a position shifted downward from the tips T1 to T3 of the above, it is difficult to measure the size of the work W or perform additional machining.
本考案は上記従来の固定具に関する不具合を解決するた

であっても基準の位置に容易かつ精確に固定することの
できる固定具を提供することを目的とする。The present invention has been made to solve the above-mentioned problems with the conventional fixtures, and provides a fixture that can easily and accurately fix a workpiece having any inclined surface at a reference position. The purpose is to

において、前記受台には、前記球面凸部の中心点を通る
受面と、該受面に前記他方の部材を当接させた状態で固
定するための固定手段を設けた構成としたことを特徴と
する。For this reason, the present invention has a support base fixed to one member and a receiving base fixed to the other member, and the support base is provided with a partially spherical spherical recess of a hemisphere or less, while the receiving base is provided. The table is provided with a spherical convex portion that can be slidably contacted by being inserted into the spherical concave portion, and the spherical convex portion and the spherical concave portion are mutually arranged at an arbitrary relative angle on at least one of the support table and the receiving table. adsorption,
In a fixture provided with a magnetic force generating means for fixing and fixing the one member and the other member at a relative angle freely, the receiving base has a receiving surface that passes through a center point of the spherical convex portion. And a fixing means for fixing the other member to the receiving surface in a state of being in contact with the other member.
上記構成によれば、一方の部材に支持台が固定され、こ
の支持台には磁力発生手段により受台が固定され、この
受台には、固定手段によって他方の部材がその受面に当
接された状態で固定される。ここで、この支持台と受台
とは、両者の球面凹部と球面凸部との摺接動作を経て任
意の相対角度で吸着、固定されるので、一方の部材と他
方の部材とは結果的に任意の相対角度で固定される。According to the above configuration, the support base is fixed to one member, and the receiving base is fixed to the support base by the magnetic force generating means, and the other member is brought into contact with the receiving surface by the fixing means. It will be fixed in the fixed state. Here, since the supporting base and the receiving base are adsorbed and fixed at an arbitrary relative angle through the sliding contact operation between the spherical concave portion and the spherical convex portion of both, one member and the other member are consequential. Fixed at any relative angle.
しかも、他方の部材が当接される受面は球面凸部の中心
点を通る面であり、この中心点は受面の傾斜角度に関係
なく、すなわち受台を支持台に対して任意の相対角度に
傾斜させても常に一定の位置に固定される点であるの
で、他方の部材の基準点をこの中心点に位置合わせした
状態で当該他方の部材を受面に当接させて固定すること
により、上記基準点の位置は当該他方の部材の曲面形状
に関係なく常に一定の位置に固定される。すなわち、他
方の部材はその曲面形状に関係なく、基準点を常に一定
の位置に固定された状態で固定される。Moreover, the receiving surface with which the other member is abutted is a surface that passes through the center point of the spherical convex portion, and this center point does not depend on the inclination angle of the receiving surface, that is, the receiving table is relative to the supporting table at any relative position. Since it is a point that is always fixed at a fixed position even if tilted at an angle, fix the other member by abutting it on the receiving surface with the reference point of the other member aligned with this center point. Thus, the position of the reference point is always fixed at a fixed position regardless of the curved surface shape of the other member. That is, the other member is fixed with the reference point always fixed at a fixed position regardless of the curved surface shape.

持台４に吸着固定されている。The work W is set on the fixtures A1 to A3. In this set state, the work W has a holding force Φ 2 of the second magnet 9 in a state in which the respective reference points P1 to P3 are aligned with the center of gravity p1 to p3, respectively, and is in contact with the upper surface 9a of the second magnet 9.

２が傾斜しても移動しない。Here, prior to placing the work W on the positioning jig D, the center of gravity p1 to p3 of each of the fixtures A1 to A3 is preset to be at a standard height from the upper surface of the surface plate C. Therefore, when the work W is placed, each reference point P1 to
Each P3 is fixed at the standard height (center height).
Moreover, each center of gravity p1 to p3 once set to the standard height is

る。After the measurement is completed, the work W can be removed from the positioning jig D by pulling the work W upward with a force larger than the holding force Φ2 of the second magnet 9. Since the holding force Φ1 of the first magnet 12 is larger than the holding force Φ2 of the second magnet 9, the pedestal 2 and the support base 4 are not separated when the work W is pulled upward. The holding force Φ2 of the magnet 9 is released and the work W is reliably separated from the fixture A.
